A pair of upright guide posts 92 are lo cated upon the bed plate, beyond the gum reservoir, said guide posts being equally spaced from the longitudinal center of the bed plate. Slidably mounted upon the guide posts is the sliding h aid 93. an arm 94 projecting at an angle from saidsliding head, the free extremity of said arm being mounted upon the reciprocating rod 95, said rod being provided with an enlarged head 97 at its upper extremity against which the arm 94 is held by means of the spring 98 interposed between said arm 94 and the upper edge of the tubular bearing 99 which is fixed upon the bed plate and through w ng at their lower GXtItllllilPz: the plate 1 2;. A carton clamping frame 103 is can r al near the rear extremity of the plate 1 1'2 and a somewhat similar frame 104 is varried near the forward extremity of said plate. said frames being disposed transversely to said plate. The plate 102 is provided with recesses 10.} and 106 located ad jacent the frames 11).; and 10-1 respectively, said recesses being, for the purpose of receiving the rartons as will be hereinafter described.

The clamping frame 103 comprises the mp plate 107 secured upon the upper edge f the plate 104 by means of screws or their equivalents. said top plate being, provided at the cud adjacent the gum reservoir with a short downwardly disposed flange 108 provided at its lower edge with an outturned por ion 102) beneath which the bars of gum are passed during the operation of filling the carton. At the opposite and of the plate 10]- is a down-turned flange ll 'l'ol' greater length g'han the flange lots and arranged to :h'i. as a stop to limit the movement of the bar, or sticks of gum as they are shoved into the carton by means of the ejector plate. A pair oi downwardly disposed lingers 111. is located near each extremity of the plate 10?. said illlL'tl'S being adapted to pass down upon each side of the carton being filled and in close proximity to the side faces of the feed bar. The fran'ie 104 comprises the top plate 112 which is mounted upon the upper edge of the plate 102 and is provided near each extremity with a pair of dowlrturned fingers 113 wider than the fingers 111, said lingers being arranged to pass down upon ea .11 side of the carton durin' the operation of folding the flaps upon the carton.

The shaft is provided at a point near the opposite extremity from the pinion 22 with a disk 114, said disk being provided with a cam track 115 within which the roller 116 is arranged to travel, said rolled being mounted upon one extremity of the lever 11?, which lever is pivoted at 118 upon a bracket 119 depending downwardly from the be d plate. The opposite extremity of the lever 11? is provided with a slot 120 through which is mounted the pin 121 carried upon thelower extremity of the reciprocating rod 95. Thus it, will be seen that as the cam oscillates the lever 117 the rod will be recip-. rocated, and through the arm 91 the sliding head 93' will be caused to reciprocate upon the guide posts 92. v

The sliding head 93 is provided intermediate its extremities and upon its under side with a cut out portion forming shoulders 122 near either extremity of said head and pivoted as at 123 upor each of said shoulders isa pair of jaws 124. The jaws of each pair are provided upon their adjacent edges with the curved cam portions 125, the lower extremity of each jaw being provided with an inwardly disposed finger 126 arranged to contact with the inner flaps of the carton and fold said flaps as will be hereinafter described.

A shaft 127 is journaledthrongh the guide posts 92 and is provided with a pair of cam members 128, elliptical cross section, one of said cam members being located between each pair of jaws 124. An anti-friction roller 129 is mounted at each side of each of the cams 128, said rollers bearing against the curved surfaces 125 of the jaws, a Coil spring 130 connecting each pair of jaws. preferably at a point beneath the shaft 127 holding the jaws at all times in contact with the rollers upon the cam members.

A collar 131 is fixed upon one extremity of the shaft 127 and provided with a rock arm 132 which is connected by means of the link 133' with the rock arm 134 fixedly mounted upon the shaft 135, said shaft being journaled in a suitable bearing 136 which depends downwardly from the bed plate. An arm 137 is fixed to the other extremity of the shaft 135 and proyided,

upon its free end with a roller 138, said roller arranged to ride upon the edge of the annular flange 139. which is provided upon the forward face of the disk 89. A break provided in the flange 139, one'extremity of, said flange being cut oil abruptly as at 140 whiie the other extremity is tapered gradually toward the disk 89 as shown at 141. As the roller 138 rides upon the edge of the flange 139 the cam members 128 will be held in the position best illustrated in Fig. 13, but as the extremity 140 of the flange passes beneath the roller. the arm 137 will be rocked bringing the roller-into contact with the face of the disk 89, the cam members 128 being rocked into a vertical po sition allowing the springs 130 to bring the jaws 124 together and the jaws will be held in this position until the roller passes up the int-lire 141, and on to the edge of the flange 139 again.

For the purpose of turning up the end portion of each of the closing flaps of the cartons a pair of blocks 142 are located upon the bed plate in alinementwith the guide bars 49. As both of said blocks are identical in construction with the exception that they are made right and left it, is only thought necessary to describe one of the blocks. Each block is provided along the edge toward the center of the bed plate with an lip-standing rib 143. the rear portion of said rib and the block being beveled as shown at 144. A plate the form of which is best illusti atcd in Fig. 16 is providcd at its: uppenwlge with an over-turned flange 146 which rests upon the top of the rib 143 and is connected thereto by means of screws 147. The free extremity of the plate 145 is tapered and provided with a rounded under edge as shown and the opposite extremity of said p5 to beneath the flange 146 is provided with a V-shaped notch 148. Each of the plates 145 is spaced away from the rib 143 as illustrated in Fig. 17 thus allowing room for the up-turned extremity of the flap to pass between said plate and rib. An off-set portion 149 is provided upon the forward extremity of each of the ribs 143, the under side of said extension being curved forming an arc of a circle as shown at 150, a rib 151 being provided through the center of said curved portion, said rib being eccentric thereto.

An aperture 152 is formed in the bed plate beneath each of the extensions 149 and pivotally mounted within each of said apertures and concentric with the are 150 is a gate 153, arranged to be oscillated beneath said off-set extension as will be hereinafter described. Each gate is pivotally connect-' ed by means of a link-154 with a reciprocating rod 155 slidably mounted through a suitable aperture 156 within the stationary block 157, an anti-friction roller 158 being carried by each of the rods 155 and located within one of the inclined grooves 159 in the horizontally slidable block 160, said block being provided with the reduced extensions 161 and 162 which are slidably mounted within the bearing brackets 163, supported from the bed plate, said block 157 being also mounted upon said brackets.

A disk 164 is fixedly mounted upon the shaft 3, a cam track 165 being provided in the forward face of said disk. A lever 166 is pivotally mounted at its lower extremity upon the shaft 61, the upper extremity of said lever being pivotally connected by a link 167 to a reduced portion 162 of the sliding block 160. Intermediate the extremities of the lever 166 is mounted an anti-friction roller 168 which is received within the cam track 165 and arranged to travel therein as the disk 164 rotates. It will thus be seen that as the disk 164 is rotated the lever 166 will be oscillated. reciprocating the block- 160 and as said block is reciprocated the rollers 158 will travel in the inclined slotsone of the end flaps 0 thereof will be re-- ceived upon each of the gates which are at that time in the initial position shown in Fig. 11. As the gates are raised the flaps a. will be bent upwardly, hinging at the point where said flaps emerge from the body portioh of the carton, the up-turned ends at of said flaps riding upon the eccentric ribs 151, thus guiding said up-turned end portions of the flaps into the carton, between the upper wall of the carton and the inner flaps 1) thereof, the closed carton as illustrated in Fig. 21 being then ejected from the machine as will be hereinafter described.

A discharge platform 170 extends outwardly from the forward extremity of the bed plate in a position to receive the filled cartons as they are ejected from the machine. The discharge platform is provided along each edge with an outwardly curved lip-standing side Wall 171 between which the filled cartons are received as they are ejected from the machine. The forward extremity of the platform is curved downwardly and a curved uard 172 is provided on each side thereof for the purpose of guiding the cartons downwardly from said platform on to the endless conveyor belt 173. said belt passing over a pulley 17% mounted on. a shaft 175 which is journaled in a bean ing 176 supported upon the uprights 177 which uprights also support the curved guards 112. A pulley 178 is mounted. upon the shaft176 and connected by means of a belt 179 with the pulley 180, said pulley be ing mounted upon the shaft 181 upon which shaft is also mounted the reiatively large pulley 182, said last named pulley being connected by means of the belt 183 with the drive pulley 184- Whichis fixedly mounted upon the shaft 23.

iv'hen it is desired to operate the machine, the clutch 6 is thrown into engagement with the pulley 5. rotating the main shaft 3 and through the beveled gears 21 and operating the shaft causing the several meml'sers of the machine to oper te as above deribed. The cartons designated by the letr in the form shown in Fig. 18 are con tained in the reservoir 8 and the bars or A .ks of gum designated by the letter are contained in the reservoir 83.

As the feed bar assumes the position shown in F at the lowermost carton in the is received into the recess 11 in iii e and. as the feed bar is moved :l'oraaniiy wt. in ihe guide plate 10 by of the r: in fl'l'ilfi' 44 and the lever and Y and 4-. i" spectireiy. the operation oi which is above desci' 5. tilt? carton thus picked up will be moved forwardly upon the bed plate 1, the end or closing flaps 1; of said carton sliding beneath the guide bars 4-9. As the carton carried to a point ed iacent the car in opening plunger; and 53 the cam disk 5?. "sill have assumed the position shown in Fig. 6, the arm 36 being operated thereby and drawing the guide plate and feed bar into their lowermost position, leaving the cartons in alinement with the carton opening plungers 52 and 53 which plunger-s are then in the position shown in Fig. 7. The feed bar 9 Will at the same time through the mechanism above described have been carried back to its extreme backward position, the transverse recess 73 in the feed bar being at this time located beneath the carton above referred to.

As the cam assumes the position illustrated in Fig. 8, causing the plungers 52 and 53 to be moved into their operative position the cam disk 33 will have rotated, bringing the feed bar into its raised position, the plungers passing into each open end of the carton and slightly opening the carton as the feed bar is raised, the trans verse recess 73 receiving the carton which is caused by this action to assume the form shown in Fig. 19. 1' The feed bar which at this time will have reached the position shown in Fig. 4 will then be moved forward the open carton which is located in the transverse recess 73 being carried therewith to a point directly beneath the clamping frame 103. As the feed bar reaches this, the forward limit of its movement, it will, by means of the guide plate, be lowered, releasing the empty carton at the same time that the sliding head 93 will be lowered by means of the cam 111 as above described, the frame 103 being carried downwardly by means of said sliding head and clamping the empty carton upon the bed plate. The ejector plate 85 will then be operated. by means of the cam 89 sliding the live lowermost bars of gum from the reservoir 1'? into the open carton, the end flange 11*) of the clamping frame preventing the sticks of gum from being passed beyond the other open end of the carton. This operation is illustrated in Fig. 1C.

The guide plate 1 7 being in the lo serial position, the feed bar 9 will have moved back to the limit of its backward movement at which time the transverse recess Tel: there- 'in will have reached a position directly beneath the clamping frame 103 containing the carton which ias past been filled. its the sl ding in ii 3 3 is. raised in the manr 2* herea tore maarribed, carrying 1' es'ewith the claz'njiiing frame H3 and the iilieri carton the guide plate Win be 3 mad carry ing the feed bar therewith, s: (i carton being received in the transverse recess 74., Upon the next fm'ward movement of the feed bar which still remains in the raised position, the carton ill be carried forward upon the bed plate, the extremities of the closing flaps a being revolved between the ribs 143 and. the plates H5. Asthe closing flaps are thus passed between the an; and

plates above named the extremities of the neath the roller 138 feed bar plungers, an article in Fig. 20. The feed bar will reach the limit of its forward movement bringing the carton to rest beneath the clamping frame 104 and as the feed bar is lowered, releasing the carton, the. sliding head 93 will at the same time be lowered, the clamping frame .104 engaging the carton. After the extremity 140 of the cam track 139 passes bethe arm 137 will be rocked, the cam members 128 being rocked into a vertical position as above described, the jaws 124 being drawn together by means of the coil springs. As the jaws 124 are closed the fingers 126 thereon will engage the inner flaps b of the carton folding said flaps inwardly, the carton then appearing as shown in Fig. :20. As the inclined portion 141 of the cam flange 139 passes beneath the roller 138 the roller will be caused to ride up on the edge 139 rocking the arm 137 into the normal position, causing the jaws 124 to be opened as shown in Fig. 13. The end or closing flaps 0 are at this time restin upon the gates and as the block 100 is moved into the position shown in Fig. 12 the rods will be raised by means of the inclined tracks 159 thus raising the gates and closing the end flaps 0, the carton then appearing as indicated in Fig. 21. The sliding head 93 at this point, will raise, causing the frame 104 to release the filled and sealed carton and as the feed bar 9 is carried forward in its next operation the buttons 1555 upon the forward end of the will engage the carton moving it forward to the discharge platform. Upon each forward movement of the feed bar a folded carton is carried from the carton reservoir to the carton opening plungcrs, an opened carton is carried, in the recess 73 from the plungers to the clamping frame 103 preparatory to being filled. the latest filled carton is carried in the recess 71 from the gum reservoir to the clamping frame 104, where the flaps are closed as above described and the preceding carton is moved toward the discharge platform by means of the buttons 133. The finished articles are thus one at a time dropped from the dis charge platform on to the endless carrier belt 173 and carried away from the machine.
